pH and pKa relationship for buffers | Chemistry | Khan Academy

[@garrettramos4044]

This was GREAT! I couldn't wrap my head around how to manipulate the equation to find the ratio of base to acid. All the other info I saw kept using examples with "live" figures. You explaining it without any specific numbers involved made it so much easier to see the relationships and follow the concepts. THANKS!!!!!!!!!!

Oh wow, this makes so much sense now! I always had such a hard time remembering if pH>pka would protonate or deprotonate a molecule and this suddenly helped make things click.

[@shubham_mahi]

When pH > pKa, Then, [HA] > [A-] You told exactly opposite, everything else is perfect💯👍

[@raanoooshh9296]

This was exactly what I was looking for!! Thanks!

[@aswingrace6980]

Thank you madam...helps me a lot😀

[@einstienabdullah3320]

Afaik , the concetration of pure water in 55.55M. so why did you avaoid that in 1:23

[@LilyGraceySa]

Thank you lots!

[@jessicalv6442]

AMAZING!!!

[@mahfuzrahman3679]

Thanks

[@thomaskosten8113]

This finally helped me understand the HH equation thank you!!!

[@Lkriese]

Awesome. Thank you.

[@neelofaransari854]

Omg thank you so much

[@eddyseid5837]

Very useful. Thank u!

[@dikshitkapil4686]

I have a question here . How is the buffering related to the ph ? Is it that when HA= A- then the ph-pka is 0 and the buffering capacity is maximum?

[@shambhaviacharya5425]

thank you so much

[@MonkeyDLuffy-xr4fl]

Omg gurlll thanks

[@Fany-rb8iu]

Thank you ! It helps me a lot!

Why do all the teachers on this channel stutter it’s really hard for students who have concentration problems.

[@getsmarttips2444]

very nice

[@LiveYourLife229]

she sounds like flame princess from adventure time ;-;

[@jenniferfox8382]

These were so much better when Khan was explaining things. Every other video by anyone else is just a mess.

[@pickaxingoneuropa8457]

Thank You for all your help! This MAKES sense- so like 2 over 1- so 2 is greater than 1. so if A- is the numerator and HA is the denominator THEN A- is greater than the weak acid. OH THANK YOU THANK YOU THANK YOU! You ARE A GENIUS!

[@vinzky89]

Thank you so muchhhhhh

[@husseinali-ei6ft]

Mmmmmm very good

[@regularsizedpanda]

why doesn't the android app have these new videos?

[@ed_dytv7011]

Traduction in arabic please(sous titre youtube)

[@XxXanime03XxX]

What happened to the other guy???????

[@inesguett8126]

Can someone tell me what ph is like not the meaning but the ph of what

[@cesaryescas9336]

pH is saying in English terms -log is the p in pH, and H is concentration of H3O+ a.k.a hydronium.

[@adrianparvez]

In this case, she's talking about the pH of the buffer solution

[@magicalworld5302]

👍👌🥰

[@jooozey3488]

She sounds Korean

[@whoboughtthenoodles]

yo is this leah4sci?

[@aanguss]

pourquoi j'me complique la vie ici moi
